Location of the Rhythm condo right next to Phra Khanong BTS station is superb. A small 24 hour supermarket is just on the opposite side. U can also find a few bars n small restaurants nearby. Laundry is very conveniently in-house with a pick-up service at ur flat.
The rooftop swimming pool (34th floor) was tremendous with a view of most of BKK. Be aware of the high chlorine level - bring swimming goggles to avoid looking like a red-eye rabbit :-)
Gym is cool too.
My only complaint would be the noise level in the apartment. The BTS station - as great as it is to hv it in front of the door - the tunnel underneath it creates and elevates the motorcycle, TukTuk, car... noise. I had problems sleeping but than I m a light sleeper.
Many thanks to Saowanit.
